Building Collaboration Format (BCF) "The BIM Collaboration Format (BCF) allows different BIM applications to communicate model-based issues with each other by leveraging IFC models that have been previously shared among project collaborators. BCF was created for facilitating open communications and improving IFC-based processes to more readily identify and exchange model-based issues between BIM software tools, bypassing proprietary formats and workflows." BCF at Wikipedia BCF at buildingSmart
CityGML CityGML is an open data model and XML-based format for the storage and exchange of virtual 3D city models. It is an application schema for the Geography Markup Language version 3.1.1 (GML3), the extendible international standard for spatial data exchange issued by the Open Geospatial Consortium (OGC) and the ISO TC211.

Drawing Exchange Format (DXF) Drawing Exchange Format (DXF) is a file format designed by Autodesk to allow exchange with their AutoCAD software. While they publish specs it is not an open format as they alone control iterations to the format. Autodesk and the Open Design Alliance sell commercial licenses for accessing DXF files. There is generally good support for DXF is libre software. DXF at Wikipedia

Green Building XML (gbXML) "It is the language of buildings that allows disparate 3D building information models (BIM) and architectural/engineering analysis software to share information with each other" gbXML official website
GeoJSON GeoJSON is a geospatial data interchange format based on JavaScript Object Notation (JSON). It defines several types of JSON objects and the manner in which they are combined to represent data about geographic features, their properties, and their spatial extents. GeoJSON uses a geographic coordinate reference system, World Geodetic System 1984, and units of decimal degrees. GeoJson official website

RFC7946 official website

GeoPackage (gpkg) GeoPackage is an open, standards-based, platform-independent, portable, self-describing, compact format for transferring geospatial information. The GeoPackage Encoding Standard describes a set of conventions for storing the following within an SQLite database: vector features, tile matrix sets of imagery and raster maps at various scales, attributes (non-spatial data) and extensions. GeoPackage official website
GL Transmission Format (glTF) "Why we should all support glTF 2.0 as THE standard asset exchange format for game engines" on GODOT open source game engine blog.

"glTF™ (GL Transmission Format) is a royalty-free specification for the efficient transmission and loading of 3D scenes and models by applications. glTF minimizes both the size of 3D assets, and the runtime processing needed to unpack and use those assets. glTF defines an extensible, common publishing format for 3D content tools and services that streamlines authoring workflows and enables interoperable use of content across the industry."

Hierarchical Data Format (HDF, HDF4, HDF5) TODO TODO
Industry Foundation Classes (IFC, ifc, ifcxml, ifczip) "IFC is a standardized, digital description of the built asset industry. It is an open, international standard (ISO 16739-1:2018) and promotes vendor-neutral, or agnostic, and usable capabilities across a wide range of hardware devices, software platforms, and interfaces for many different use cases."

JavaScript Object Notation (JSON) TODO TODO
Open Shading Language (OSL) TODO TODO
OpenCDE "Current industry practice of data exchange between common data environments is inefficient and costly. Commercial reasons aside, CDE Vendors have real technical challenges for developing sustainable integrations." opencde at buildingSmart
Polygon File Format (PLY) TODO TODO
Radiance (hdr, rad, mat, etc) TODO TODO
1200px-SVG logo.svg.png Scalable Vector Graphics (SVG) SVG is an image format developed by the World Wide Web Consortium (W3C) for vector graphics. SVG uses an XML format and is easy to generate on the fly and edit in many programs. Inkscape and Krita are leading examples of vector graphics editors using the SVG format, but many other programs can export to SVG. TODO
Universal Scene Description (USD) TODO TODO
Extensible Markup Language (XML) TODO TODO
